A) is held unchanged to maturity.
B) is increased in size (i.e., becomes more short) after one period.
C) is increased in size (i.e., becomes more short) if the price goes down in the first period and decreased in size (becomes less short) if the price goes up in the first period.
D) is decreased in size (i.e., becomes less short) if the price goes down in the first period and increased in size (becomes more short) if the price goes up in the first period.
